ʻO nā papa hāmare o kahi mea wiliwili e wāwahi i nā mea ma lalo o ka wili wikiwiki, no laila e halihali ana i ka hopena o nā mea. ʻO nā mea e wili ʻia ai he mau mea paʻakikī kiʻekiʻe e like me ka hao hao a me ka pōhaku, no laila pono nā papa hāmare e loaʻa ka paʻakikī a me ka paʻakikī. Wahi a ka ʻikepili loea pili, i ka wā e hiki ai ka paʻakikī a me ka paʻakikī o ka mea i ka HRC>45 a me α>20 J/cm² hiki ke hoʻokō ʻia nā koi hana ma lalo o nā kūlana hana i luna.
Ma muli o nā ʻano hana a me nā koi o nā papa hāmare, ʻo nā mea i hoʻohana pinepine ʻia he kila manganese kiʻekiʻe a me ke kila pale ʻaʻahu haʻahaʻa. Loaʻa i ke kila manganese kiʻekiʻe ke kūpaʻa ʻaʻahu maikaʻi a me ka paʻakikī kiʻekiʻe. Ma hope o ka hoʻopau ʻana + ka hoʻomaʻamaʻa ʻana i ka mahana haʻahaʻa, hoʻokumu ke kila pale ʻaʻahu haʻahaʻa i kahi ʻano martensite i hoʻomaʻamaʻa ʻia a paʻakikī, kahi e hoʻomaikaʻi ai i ka paʻakikī o ka alloy me ka mālama ʻana i ka paʻakikī maikaʻi. Hiki i nā mea ʻelua ke hoʻokō i nā koi hana o nā papa hāmare.
