- Q:Aluminum and Steel brittle or ductile based on these results? and why? Steel Aluminium% Elongation 0.2510.2705Modulus of E in ksi11833.33964.71Tensile Strength (ksi)87.5 51.5Yield Strength (ksi)78.5 41
- Only steel(of this pair)might be liable to brittle fracture,which would be implied by almost zero elongation or reduction in area at fracture.On this basis the steel has not failed by brittle fracture.I would expect much more elongation in pure aluminium than your sample shows so I presume it to be brittle unless it is an alloy rather than commercially pure aluminium.However brittle fracture in metals is a particular phenomenon to be determined by impact tests and examination of fracture surfaces and is particularly relevant to metals with the body centred crystal structure.
- Q:This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.
- pl. be specific about the type of steel: (Steel is a metal alloy whose major component is iron, with carbon content between 0.02% and 1.7% by weight. Carbon is the most cost effective alloying material for iron, but many other alloying elements are also used.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and their distribution in the steel controls qualities such as the hardness, elasticity, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also more brittle. The maximum solubility of carbon in iron is 1.7% by weight, occurring at 1130° Celsius; higher concentrations of carbon or lower temperatures will produce cementite which will reduce the material's strength. Alloys with higher carbon content than this are known as cast iron because of their lower melting point.[1] Steel is also to be distinguished from wrought iron with little or no carbon, usually less than 0.035%. It is common today to talk about 'the iron and steel industry' as if it were a single thing; it is today, but historically they were separate products. Currently there are several classes of steels in which carbon is replaced with other alloying materials, and carbon, if present, is undesired. A more recent definition is that steels are iron-based alloys that can be plastically formed (pounded, rolled, etc.). Iron alloy phases : Austenite (γ-iron; hard) Bainite Martensite Cementite (iron carbide; Fe3C) Ferrite (α-iron; soft) Pearlite (88% ferrite, 12% cementite) Types of Steel : Plain-carbon steel (up to 2.1% carbon) Stainless steel (alloy with chromium) HSLA steel (high strength low alloy) Tool steel (very hard; heat-treated) Other Iron-based materials : Cast iron (2.1% carbon) Wrought iron (almost no carbon) Ductile iron)
- Q:How are steel coils inspected for bendability using bend testers?
- Bend testers are specialized machines utilized to inspect the bendability of steel coils, measuring their flexibility and resistance against bending. The inspection process involves multiple steps to guarantee precise and dependable outcomes. To begin with, the steel coil is prepared by securing it firmly in place, typically using clamps or other mechanisms to prevent any movement during testing. This ensures stability and enables consistent and repeatable measurements. Following that, the bend tester is set up according to the specified testing parameters. These parameters usually include the desired bend angle, the speed at which the bend is applied, and the number of cycles to be performed. The bend tester is equipped with a bending mechanism that applies a controlled force on the coil, simulating the bending conditions it may experience in its application or use. Once the bend tester is ready, the bending process commences. The machine gradually applies an increasing force to the steel coil until it reaches the desired bend angle. Careful measurement and monitoring of this force take place throughout the process to ensure accuracy. While the bending process is underway, the machine records and displays significant data, such as the applied force, the angle of bend, and any indications of cracking or other defects. This data is crucial for evaluating the bendability of the steel coil and determining its compliance with required standards. Once the desired bend angle is attained, the coil is released from the bending mechanism, allowing any residual stresses to relax. This relaxation period is essential for observing any potential spring-back effect, where the coil partially returns to its original shape after bending. The amount of spring-back is also measured and recorded for further analysis. Finally, the inspection results are analyzed to assess the overall bendability of the steel coil. If the coil meets the specified bendability criteria, it can be deemed acceptable for its intended application. However, if any cracks, fractures, or excessive spring-back are detected, further investigation and analysis may be necessary to identify the cause and determine appropriate corrective actions. In conclusion, bend testers play a crucial role in inspecting the bendability of steel coils. Through a controlled and systematic process, these machines accurately measure flexibility and resistance to bending, ensuring the quality and reliability of steel coils used in various industries.

- Q:I have a Charles Daly shotgun and I'm trying to find out if it is ok to shoot steel out of. The side engravings say: Charles Daly 20 GA 3 and the other side says : KBI-HBG, PA made in TurkeyOn their website it says that the barrel on the Charles Daly 300 Field is able to shoot steel but I don't see anywhere that this is a 300 model.Im also not sure if the choke is able to shoot steel. It has no engravings on it. How can I tell if this choke will work? It is the original choke that came with the gun?
- If it has removable choke tubes, just get a MOD or IMP CYL and it will work. If it is a fixed choke, depending upon how old it is, the barrel may be too thing and steel could damage the barrel. If the shotgun is less than 20 years old and with a MOD or more open choke, you should be good to go.
- Q:What would be a better knife one with damascus steel or one without? Why is damascus steel so special other than the look? And why do some people say high carbon steel is better than regular? mainly though I want to know about the damascus. Thanks, max points to best answer.
- Damascus steel was a great steel in it's time. Because it was one of the few ways to make good steel from iron. But today there are much better steels available. Damascus steel was a very labor intensive process, a single knife would cost many thousands of dollars today. The Damascus steel knives are not actually Damascus steel, the pattern is etched on or engraved on. In fact the Damascus steel knives I saw reviewed on Consumer Reports are ceramic blades, not even steel at all. Bottom line, any Damascus steel knives are just a pattern on standard steel, no different from the others. It's a marketing gimmick.
