Ka hopena o ka Cerium ma nā waiwai o ka Tin Phosphor Bronze Alloy

Ua hōʻike nā hoʻokolohua i ka mana o ka cerium ma ka microstructure o katin-phosphor keleaweQSn7-0.2 alloy i hooleiia, homogenized a recrystallized.E ʻoi aku ka maikaʻi o ka mesh, a ua hoʻomaʻemaʻe ʻia ke ʻano o ka palaoa ma hope o ka annealing deformation.ʻO ka hoʻohui ʻana i kahi liʻiliʻi liʻiliʻi o ka cerium honua hiki ke hoʻomaʻemaʻe i nā haumia ʻino i loko o ka huila a i ʻole e hoʻopau i kona hopena pōʻino, a hiki ke hui pū ʻia me ke keleawe e hana ai i nā pūhui intermetallic CuCeP, i hoʻopuehu ʻia i loko o nā palena palaoa a i ʻole nā ​​​​palapala.ʻO kēia mau ʻāpana ʻelua, i māhele ʻia i nā wahi ʻeleʻele liʻiliʻi, hoʻomaʻemaʻe i ke ʻano huila, a ʻo ka hoʻohui ʻana o ka cerium e hoʻomaikaʻi nui i ka ikaika a me ka paʻakikī o ka alloy, a ua hoʻoholo ʻia ʻo ka nui o ka cerium i loko o ke keleawe keleawe he 0.1% -0.15%, e hoʻomaikaʻi maikaʻi ana i ka hana piha o ka ululāʻau keleawe keleawe, a mele i ke ola lawelawe o ke keleawe keleawe.
ʻO ka paʻakikī paʻakikī o ke keleawe phosphor tin a me ka pilina ma waena o ka ikaika tensile a me ka elongation o nā specimens sheet a me ka cerium content.E piʻi aʻe ka ikaika a me ka paʻakikī o ke keleawe phosphor tin me ka piʻi ʻana o ka ʻike cerium o ka huahana, akā inā ʻoi aku ka nui o ka cerium ma mua o 0.125%, ʻaʻole e piʻi nui ka ikaika a me ka paʻakikī o ka huahana;piʻi ka elongation me ka ʻike cerium.Ua emi iki ka piʻi ʻana o ka leo.Ke noʻonoʻo nei i ka hoʻomaikaʻi ʻana i nā waiwai mechanical o ka alloy, ʻo ka ʻike cerium maikaʻi loa o ke keleawe phosphor tin he 0.1% -0.15%.Inā kiʻekiʻe loa ka nui o ka cerium, e emi nui ana ka plasticity o ka alloy;inā haʻahaʻa loa ka ʻike cerium, ʻaʻole e koʻikoʻi ka hopena hoʻoikaika o nā mea ʻenehana honua ma luna o ka alloy.
