The following results are achieved : ( 1 ) in accordance with the empirical electron theory of solids and molecules, considering the number of covalent bond pairs on the strongest bond in a segregation structure na, the elements for matrix - strengthening can be chosen. ( 2 ) on the basis of the available phase - equilibrium thermodynamics calculation of alloy system and phase diagrams, which have been worked out, the contents of alloy elements can be identified with reference to the types, quantity and phase - transformation of carbides. ( 3 ) both the values relating to toughness ( including bending strength, yield strength, impact value of unnotched samples ) and hardness of new dm9 die steel are higher than those of crl2mov die steel
