Iwo ma mechanical properties anowanikwa nekuita bvunzo pazvienzaniso kwete pachinhu chacho. Kana chinhu chemuviri chiri chikuru uye chakakosha, hachigone kukuvadzwa pakuongororwa. Kuedza kusiri-kunoparadza inzira yakadaro isingakuvadzi chinhu.
Non-destructive test (NDT) seti yenzira dzehunyanzvi dzinoshandisa hunhu hweruzha, mwenje, magineti uye magetsi, pasina kukuvadza kana kukanganisa mashandiro echinhu chakaongororwa, kuona kana paine chakakanganisika kana kuti inhomogeneity muchinhu chakaongororwa, inopa ruzivo rwakadai sehukuru, nzvimbo, hunhu uye huwandu hwechinhu chakakanganisika uye chitarisiko chechinhu chakatariswa. anokwanisa kana ane hupenyu hwasara, nezvimwewo).
Nzira dzinowanzo shandiswa dzisiri -dzisiri kuparadza dzinosanganisira kuyedza radiographic, ultrasonic test, magnetic particle test uye liquid penetrant test. Dzimwe nzira-dzisiri dzekuparadza dzekuyedza dzinosanganisira kuyedza eddy ikozvino, acoustic emission test, thermal imaging/infrared test, leakage test, alternating field measurement technology, magnetic flux leakage test, kure{3}}field testing, etc.
Vashandi vari mukuyedza-kusingakuvadzi vanofanirwa kudzidziswa hunyanzvi uye kuwana zvitupa vasati vakwanisa kubata zvitupa zvebasa.
