Alloys Of The Al

Aluminum alloys of the Al-Mg system are widely used in automotive and aviation industries due to their combination of strength, good ductility and corrosion resistance. Increasing the percentage of magnesium leads to higher strength of the material with a slight reduction of ductility. Behavior of critical stresses in materials were studied under variable strain rate loading conditions. The possibility to predict critical dynamic stresses of materials based on a structural-time approach is discussed.

Strain Rate Loading

The effect of varying the strain rate loading conditions in compression on a copper single crystal dispersion-hardened with SiO2 particles has been examined. These particles appear as small spherical inclusions in the copper lattice and have a volume fraction of 0.6%. The structure of representative crystals was examined prior to any testing on a transmission electron microscope (TEM) to determine the nature of the dislocations initially present in the tested crystals. Only a few scattered edge and screw dislocations were viewed in those specimens.

Abstract AISI 4032 is a molybdenum alloy steel of moderate hardenability. It is used extensively in the automotive industry. This steel combines moderate strength and hardness with good ductility and toughness in the quenched-and-tempered condition because it is relatively free from temper embrittlement when tempered in the range 850-1100 F. Among its many uses are nuts, bolts, studs, machinery parts and fasteners for the transportation and other industries. AISI 4032H is a similar steel except that it has a slightly wider range of carbon and manganese. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-411.
