Materials Analysis of arsenic and lava Matco materials specialists examine indian artifacts on loan from a museum and try to determine the spiritual properties of lava
Metallurgical Examination of Indian Artifacts Prehistoric Indians developed a way to form tools by what could be called a sheet metal technique.
Metallurgical Characteristics of Hydrogen Damage Prolonged exposures to a hydrogen producing environment at temperatures in excess of 200° C can result not only in severe decarburization, but also in the formation of methane gas.
Cracking of low sulfur steel in cold weather Sulfur lowers the brittle transition temperature and results in steel being unable to withstand an impact type load in cold weather.
Stress Corrosion Cracking and Corrosion Fatigue Both stress corrosion cracking and corrosion fatigue are surface initiated and appear to be brittle, with very little macroscopic evidence of deformation.
