Heat Treatment of Orthodontic Steel Wire
A study was made to ascertain the effect of heat treatment, at a time-temperature ratio of three minutes at 900 F., on orthodontic 18-8 and Elgiloy steel wire with respect to the followings a) the ability of a vertical loop to resist permanent deformation when subjected to a tensile load; b) the …

Heat Treatment of Ozark Cherts: An Archaeological Experiment in the Effects of Heat Treatment on Toolstone Flaking Properties
… stone tool production. I hypothesize that people heat-treated Burlington as well as Jefferson City chert to improve the flaking qualities of the cherts. Ideally, the process of heat treatment improved the flaking qualities of the raw materials by exposing the raw material to heat for an extended …

Microstructural analysis of aluminium alloy 2096 as a function of heat treatment.
A detailed microstructural investigation into possible metallurgical culprits of stress corrosion cracking (SCC) of Al-Li-Cu alloy AA2096 was carried out as a function of isothermal aging time at 160°C. Two tempers were analysed for this study: under-aged at 4 hours (UA4) and under-aged at 12 hours …
