Hiʻona
ʻO GH99 kahi Ni-Cr e pili ana i ka ua paʻakikī paʻakikī deformation kiʻekiʻe kiʻekiʻe o ka alloy, hiki ke hoʻohana ʻia no ka manawa lōʻihi ma lalo o 900 ° C, a hiki i ka manawa pōkole ke kiʻekiʻe o ka mahana i 1000 ° C. Hoʻoikaika ʻia ka GH99 alloy ma ka hoʻohui ʻana i ka chromium, cobalt, tungsten a me ka molybdenum no ka hoʻoikaika ʻana i ka hopena paʻa, ka alumini a me ka titanium e hana i nā ʻano hana kahiko, a me ka boron, cerium a me ka magnesium e hoʻomaʻemaʻe a hoʻoikaika i nā palena o ka palaoa. ʻO ka GH99 alloy he kiʻekiʻe ka ikaika wela, ka paʻa o ka hui, a loaʻa iā ia ka hana wela a me ke anu anuanu a me ke kaʻina hana hoʻoheheʻe. Me ka alloy i hana ʻia e ka pā nui, hiki ke hoʻohana pololei ʻia ma hope o ka hoʻonā paʻa Hoʻomaʻamaʻa me ka ʻole o ka ʻelemakule. ʻAʻole i ʻike ʻia ka huila i nā ʻāpana pōʻino ma hope o ka ʻelemakule lōʻihi ma 700 ℃ ~ 950 ℃.
