The Effect of Sintering Parameters on the Densification Behavior of PM High Speed Steel
분말 고속도공구강의 소결 조건에 따른 치밀화 거동연구
Abstract
The densification behavior during a sintering of M2 and T15 grade high speed steel powder compacts was reported. Sintered densities over 98% theoretical were achieved by a liquid phase sintering in vacuum for both grades. The optimum sintering temperature range where full densification could be achieved without excessive carbide coarsening and incipient melting was much narrower in M2 than in T15 grade. The sintering response was mainly affected by the type of carbides present. The primary carbides in M2 were identified as
