It is shown that the high hardness and low thermal conductivity promote the formation of transformed asbs, and the deformed asbs will form if low hardness and high thermal conductivity are involved ; for steel with both high hardness and thermal conductivity, the transformed asbs will transform into deformed ones, due to that the fast heat conduction from high temperature asbs results in rapid temperature rise around and thus decreasing the hardness
研究結果表明:鋼的高硬度和低熱導率有利於形成相變帶;反之,則傾向于形成變帶;對于具有高硬度和高熱導率的鋼,由於高溫相變帶區域的熱量迅速傳遞到周圍的基體組織而使其溫度升高、硬度降底,形成的相變帶會向形變帶轉化。Numerical results are obtained for velocity, temperature and concentration profiles, variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90. at a given inclination angle, heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values, and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum
研究結果表明:傾斜角度一定,當熱浮力與物質擴散浮力共存且二浮力之比b從較高正值變化到較高負值時,流體速度和熱質傳遞速度從高逐漸變低並出現最小值,此後隨著向下浮力的增大,流體向下流動且隨| b |的增大而加速,熱質傳遞速率隨| b |的增大而重新增大。The thermal network model of steady - state temperature field of swing movable teeth reducer is set up. the calculation models for power losses, heat transfer and thermal resistance of swing movable teeth reducer are established. the thermal network figure of swing movable teeth reducer is drawn
