对各种钢号温挤过程参数的研究,将促进这种先进的压力加工方法在工业中更广泛地应用。本文探讨了下列问题: 1.用数学布点试验法来研究合金钢20X,20XH 3 A,45Γ 2,12 X 2 H 4 A的温挤力的参数。 2.建立单位压力与变形程度及温度之间的经验分析式。 3.研究上述钢号温挤后的机械性能。用类似于在文献中所介绍的方法,取对数变形程度ε=0.223,0.570,0.916,1.263,1.609以及温度为400,500,600,700,800℃的各点来研究单位压力与变形程度及温度的关系。温挤力的参数研究中的数学布点,沿用文
Research on the temperature extrusion process parameters of various steel grades will promote the application of this advanced pressure processing method in the industry. This article explores the following issues: 1. Using mathematical placement test method to study the temperature extrusion parameters of 20X, 20XH 3 A, 45Γ 2,12 X 2 H 4 A alloy steel. 2. Establish the unit of pressure and deformation degree and the empirical analysis between the temperature. 3. Study the mechanical properties of the above steel temperature squeeze. The relationship between unit pressure and degree of deformation and temperature was studied by using points similar to those described in the literature with logarithmic degrees of deformation ε = 0.223, 0.570, 0.916, 1.263, and 1.690 and temperatures of 400, 500, 600, 700 and 800 ° C. Temperature squeeze parameters in the study of mathematical distribution, follow the text
