    研究W-Cu粉末軋制生坯制備流程的客觀化判據(jù),初步得到W-Cu粉軋生坯制備的客觀方法框架?;诨炝吓ぞ氐淖兓厔?shì),確定粉末與粘結(jié)劑的最佳配比?;诓顭?熱重分析結(jié)果,確定粉體的烘干溫度和烘干時(shí)間?;谫|(zhì)量守恒定律,確定粉軋生坯的致密度。研究方法以材料自身的物理和化學(xué)特性指標(biāo)為依據(jù),能夠很大程度減少人為因素的影響,提高粉軋生坯制備流程的穩(wěn)定性。

    Abstract:

    Objective criterion for the preparation process of W-Cu green sheet by powder rolling was investigated, and an objective methodology frame for the preparation was obtained. Based on the change tendency of mixed behavior, the optimum ratio between powder and adhesive was obtained. Based on differential thermal and thermo-gravimetric analysis results, the drying temperature and drying time of powder was determined. Based on the law of conservation of mass, the density of the powder-rolled green sheet was determined. According to materials’ own physical and chemical property index, the effect of human elements can be weakened, and thus the stability of preparation process of green sheet by powder rolling can be increased.
