• Aged alloy powder
  时效合金粉末
• This metal alloy was the first step in the development of a series of space - age alloys
  这种金属合金，是后来所发展的一系列的太空时代合金的第一步。
• Influences of electric field applying during solution process on mechanical properties , fracture characters and precipitates in aged alloys are studied
  研究了固溶过程中施加的电场对合金时效后的性能、断裂特征和析出相的影响。
• Raised , conical seat prevents solids build - up from interfering with seal . seat is hardfaced with stellite to meet severe service . alternative space age alloys are also used
  凸起的、锥形阀座避免实心颗粒淤积影响密封。阀座采用钨铬钴合金进行硬面处理，能够经受恶劣环境的考验。也可采用航空工业用合金制作的阀座。
• It is found that the electric , field improves elongations in 2090 and 2090 + ce alloys markedly , especially in 2090 alloy , but has little effect on strengths . at the same time , the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation . besides , the electric field makes both average particle size and its distributing range of 8 " phase smaller , and reduces the half width of pfz in aged alloys
  研究表明：固溶电场可显著提高2090合金及2090 + ce合金的延伸率，尤其是对2090合金，但对强度则无明显的影响；同时，固溶电场减少合金的沿晶分层断裂比例，并增加穿晶断裂及微区塑性变形；固溶电场还使合金时效后相颗粒的平均尺寸减小、尺寸分布范围减小，并使pfz的宽度减小。
