In this paper , the dislocation in 50mm cz sapphire crystal had been observed by chemical etching with metallograph and sem

The composite roll of high speed steel has the synthetical life of over ten times more than traditional high cr cast iron roll . now the research and production of the high speed steel for roll are very drastic . in this thesis , the microstructure , heat treatment and performance of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) are studied systematically by using metallograph , method of lattice , xrd , sem , eds and hardness
