GCr15 Alapai hao hao

ʻO nā waiwai kino o ka hao hao nui ka microstructure, decarburized layer, non-metallic inclusion and macrostructure.ʻO ka maʻamau, hāʻawi ʻia nā huahana e ka annealing rolling wela a me ke kahakaha kiʻi anu.E hōʻike ʻia ke kūlana hoʻouna ma ka ʻaelike.Pono ka macrostructure o ke kila me ka ʻole o ka shrinkage cavity, subcutaneous bubble, wahi keʻokeʻo a me ka micro pore.ʻAʻole ʻoi aku ka nui o ka porosity waena a me ka porosity maʻamau ma mua o ka papa 1.5, a ʻaʻole e ʻoi aku ka hoʻokaʻawale ʻana ma mua o ka papa 2. ʻO ke ʻano annealed o ke kila e hoʻokaʻawale like ʻia ka pearlite fine-grained.ʻO ka hohonu o ka decarburization layer, non-metallic inclusions a me ka carbide unevenness e hoʻokō me nā kūlana aupuni kūpono.
