Hoʻololi i nā waiwai o ke keleawe chromium zirconium ma hope o ka mālama ʻana i ka wela

Ma hope o ka hoʻoponopono ʻana i ka wā kahiko, hoʻohele ʻia nā ʻeleʻele maikaʻi ma nā palena o ka palaoa.keleawe chromium zirconium, a ua puunaueia na eleele liilii he nui iloko o ka palaoa, me ka nui o kahi mau microns.I ka emi ʻana o ka mahana, hoʻokokoke ka ʻalihi i ka ʻaoʻao keleawe, a ʻo kona solubility he 0.03% wale nō ma 400 °C.I kēia manawa, hoʻoheheʻe ʻia nā ʻāpana hui keleawe zirconium i ka hopena paʻa.No laila, ʻo ka chromium me ke kino-centered cubic structure, chromium me kahi kokoke-packed hexagonal structure, and copper with a face-centered cubic structure is almost immiscible ma ka lumi wela, akā, ʻaʻole hiki i ke keleawe a me ka chromium ke hana i nā pūhui, ʻoiai ke keleawe a me ka zirconium hiki ke hana i nā ʻano hui like ʻole.Hiki i ka Chromium a me ka zirconium ke hana i nā ʻano hui like ʻole.Ma hope o ka mālama ʻana i ka wela, ʻo ka matrix o ka chromium zirconium copper he keleawe, a ʻo ka pae ua ʻo ia ka hui intermetallic o Cr phase a me chromium.
ʻO ka ikaika tensile, ka ikaika a me ka paʻakikī o ka chromium-zirconium-copper ma hope o ka hoʻomaʻamaʻa wela e hoʻonui ʻia, a hoʻemi ʻia ka elongation ma hope o ka haki.Hoʻokumu ka chromium-zirconium-copper i kahi hopena paʻa supersaturated i ka wā o ka hoʻonā paʻa, a ʻo ka lua a me nā pūhui keleawe e hoʻoneʻe ʻia mai ka hopena paʻa i ka wā o ka wā ʻelemakule.ʻO ka ua, hoʻoikaika i ka hoʻopuehu hou.Hoʻopuehu ʻia ka māhele ʻelua a māhele ʻia i loko o ka matrix e hana i kahi pilina pili me ka matrix.Aia kekahi mismatch nui ma ka pilina pili, ka mea e hoʻoheheʻe ʻia ai ka lattice, e hoʻonui ai i ka ikehu elastic strain o ka interface phase a hoʻomaikaʻi i ka ikaika, paʻakikī a me ka elasticity o ka alloy..ʻOi aku ka kiʻekiʻe o ka conductivity uila o ka chromium zirconium copper ma hope o ka mālama ʻana i ka wela ma mua o ka mālama ʻana i ka wela.E like me ke kumumanaʻo o ka hoʻonā paʻa paʻakikī paʻakikī conductivity, ka conductivity uila o ka metala kahiko e mālama nui ʻia e ka solubility paʻa o ka matrix solution solid.Ma ka lumi wela, liʻiliʻi loa ka solubility o nā mea hoʻohui i ke keleawe.I ka wā o ke kaʻina hana ʻelemakule, ʻaneʻane e hoʻokahe mau ʻia nā mea hoʻoheheʻe ʻia mai ka matrix Cu, a e emi mālie ka ʻike o nā mea solute i loko o ka hopena paʻa a hiki i ka hopena paʻa i ka matrix keleawe maʻemaʻe, a laila e hoʻomaikaʻi ai i ka conductivity uila.
