MnCu Aloe

ʻO ka manganese copper kahi ʻano o ka alloy resistance precision, maʻamau i hāʻawi ʻia i nā uea, akā he wahi liʻiliʻi o nā papa a me nā ʻāpana, kahi ākea ākea o nā ʻano mea kani a me nā mika, i ka manawa like, he ultra ka mea. -ke kiʻekiʻe-pressure mea koʻikoʻi, hiki ke kiʻekiʻe ka palena kiʻekiʻe o ke ana kaomi e like me 500 Pa. He hopena piezo-resistive maikaʻi ke keleawe manganese a hoʻohana nui ʻia i nā ana kaomi i ka wela kiʻekiʻe. a me nā kaiapuni kiʻekiʻe e like me ka pahū pahū, nā hopena kiʻekiʻe, ka hakihaki ikaika a me ka synthesis o nā mea hou. ʻO ka hoʻololi ʻana o ke kūpaʻa keleawe manganese a me ke kaomi o waho e pili ana i ka pilina pili laina (ʻo ia hoʻi, ʻo ka piezoresistive coefficient K ua aneane mau), a he liʻiliʻi ke koena wela o ka pale ʻana, e ka manganese copper ma ke ʻano he mea koʻikoʻi i hana ʻia e nā mea ʻike, hiki ke ʻike ʻia e ke kaomi kiʻekiʻe. Hoʻololi ʻia ke ana i ke ana o ka hoʻololi kūʻē ʻana o ka manganese keleawe.
Ua hoʻohana ʻia ka hopena piezoresistive o nā ʻāpana manganese-copper e ana i ke kaomi no nā makahiki ʻoi aku ma mua o 90, a i nā makahiki 1960, ʻo Fuller a me Price, Bernstein a me Keough ka mea mua i hoʻopili i nā mea ʻike manganese-copper i ka hoʻāʻo kiʻekiʻe kiʻekiʻe (shockwave). . Ma hope o nā makahiki o ka noiʻi e hōʻike ana, ʻoiai ʻaʻole kiʻekiʻe loa ka coefficient piezoresistive o ka manganese-copper alloy, akā no ka mea he kiʻekiʻe ka naʻau, pane wikiwiki, linearity maikaʻi, liʻiliʻi ka coefficient mahana kūʻē a pēlā aku, ua kūpono loa ia no ka ka hana ʻana i nā mea ʻike ikaika ultrahigh-pressure. ʻO kona kūlana kūpono o 1 ~ 50GPa, ʻo ia ka palena kiʻekiʻe o ke ana ʻana o ke kaomi ʻana o nā mea ʻike kaomi pololei, hoʻohana nui ʻia i ka hoʻopaʻa ʻana i nā hiʻohiʻona elastic-plastic wave propagation o nā mea, dynamic fracture, layer cracking, phase transition, explosives a me nā mea ʻē aʻe. ka pahū. Eia nō naʻe, ʻo ka pale, ka pūʻali koa a me nā ʻāpana kūikawā ʻē aʻe e pono koke i nā kaomi kiʻekiʻe no ke ana pololei ʻana, a koi ʻia ka mea ʻike e loaʻa ka pane wikiwiki loa. ʻO ka holomua noiʻi o nā mea ʻike Mn-Cu i kēia mau ʻaoʻao ʻelua i hōʻuluʻulu pōkole ʻia [1].
Hoʻohana nui ʻia nā mea hoʻoheheʻe Cu-Mn i nā mea hoʻoheheʻe a pili i ka māhele o ka thermoelastic martensitic phase transition. ʻO kēia ʻano huila ma 300-600 ℃ no ka mālama ʻana i ka wela kahiko, ka hui hui ʻana i ka hui māhoe martensite maikaʻi, a ʻo ka hui māhoe martensite maikaʻi ʻaʻole paʻa loa, i ka wā e hoʻokau ʻia ai ke koʻikoʻi vibrational e hiki mai ke hoʻonohonoho hou ʻana o ka neʻe. e hoʻomoʻa i ka nui o ka ikehu, ka hana o ka hopena damping. He hopena piezoresistive maikaʻi ka manganese keleawe i hoʻohana nui ʻia i ke ana ʻana i ke ana ʻana i ke ana wela a me ke kiʻekiʻe kiʻekiʻe e like me ka pahū, ka hopena kiʻekiʻe, ka haʻihaʻi ikaika, ka synthesis mea hou a pēlā aku. ʻO ka hoʻololi ʻana o ke kūpaʻa keleawe manganese a me ke kaomi o waho e pili ana i ka pilina pili laina (ʻo ia hoʻi, ʻo ka piezoresistive coefficient K ua aneane mau), a he liʻiliʻi ka coefficient mahana pale, e ka manganese copper ma ke ʻano he mea koʻikoʻi i hana ʻia e nā mea ʻike, hiki ke hoʻomaopopo i ke ana o ka puʻe kiʻekiʻe. ana o ka hoʻololi kūʻē kūʻē manganese keleawe.
