NON-STEADY SELF-ORGANIZATION DURING SINGLE CRYSTAL INITIAL GROWTH OF SUPERALLOY DD3 UNDER HIGH TEMPERTURE GRADIENT DIRECTIONAL SOLIDIFICATLON CONDITION
高温度梯度定向凝固高温合金单晶初始生长过程非稳态自组织行为

Microstructure evolution and selection in initial transient zone of single crystal superalloyDD3 was investigated with high temperature gradient directional solidification equipment ZMLMC (temperature gradient at solid-liquid interfaCe up to 1300K/cm) wit
