x alloy meaning in English

铜铝合金

High quality single - crystal zns - based ii - vi thin films have been prepared on gaas and gap substrate using molecular beam epitaxy ( mbe ) technique . successful n - type doping of znsxse1 - x alloy using aluminum source has been carried out
本文研究了在gaas和gap衬底上，本征型和n型al掺杂zns基单晶薄膜的分子束外延生长，获得了高质量的单晶外延薄膜。
That the alloying element mn and ti substitutes the atom of fe in the rich iron - phase ( al , si , fe ) and resumes the part of the element si in primary phase refines the second phase . at the same time , the volume percentage of second phase is increased . at the course of solidification , the alternating current field changes obviously the microstructure morphology of the al - 20si - 5fe - x alloy and the number of particle eutectic structure is increased
合金元素mn 、 ti通过占据富铁相( al , si , fe )中铁原子的晶格位置，同时消耗部分初生相中的si元素，形成四元富铁相( al , si , fe , mn ) ，细化了合金中的第二相，同时提高第二相体积百分数。
