優質碳素結構和合金結構鋼.連鑄方坯低倍組織缺陷評級圖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
結果得出: ( 1 )根據固體與分子經驗電子理論,利用偏聚結構單元的最強共價鍵上的共用電子對數n _ a ,可以選擇工模具鋼基體相的強化元素; ( 2 )根據合金系相平衡熱力學計算及已有的相圖,可以碳化物類型、數量及其相變確定合金元素含量; ( 3 )新型dm9鋼在強韌性(抗彎強度、屈服強度、無缺口沖擊值)和硬度方面均高於cr12mov鋼; ( 4 )以dm9鋼與6crw2si 、 7cr2wmovsi ( dm7 ) 、 h13和cr12mov四種模具鋼的實驗比較,進一步驗證了上述冷作模具鋼合金設計方案是合適的。With the orthogonal experiment method, the heat rolling processing parameters of the high - grade carbon steel ( 20 ) are established so as to realige the control and enhance the compositive mechanical property and cold crooked performance which advances the quality of the product
