摘要：
1. With increasing content of boron and carbon the temperature of transition to the ductile state of microcrystalline strips of tool steels type R6M5 and ROM2F3 shifts into the range of higher temperatures. 2. the increased ductility of strips after annealing at higher temperatures is due chiefly to the reduced microhardness of the alloy, the increased grain size and particle size of the second phase, and also to stress relaxation. © 1991 Plenum Publishing Corporation.
