Say Manunan Mekanikal iran Kablian na Nickel-based Alloys

No manguusar na nickel-alloy materials, kaukolan tayon talosan nin unona iray mekanikal a kablian da pian naamtaan no kasin makasumpal iratan ed pigaran kakaukolanen na industriya. Kaiba ed sarayan mekanikal a kablian so: biskeg na panag-awit (TS), biskeg na panag-ani (YS), peles na itatatken, tan inka-malet, tan arum nira.

 

Pian naala irayan datos, kaukolan so tensile test. Say tensile test et uusaren pian naamtaan so ugali na materyal no nipaarap ed axial tensile load. Say kagawaan ya uusaren ed tensile test et tatawagen ya universal tensile machine.

 

 

Tensile strength (TS): Say sankatageyan ya stress ya nasungdoan na materyal antis ya nabuyak, saya so kritikal a balor no iner so transisyon na metal manlapud pareparehon plastic deformation ya anggad localized concentrated plastic deformation, tan saya met so sankatageyan a load-bearing capacity na metal diad silong na static tensile conditions. Say simbolo et Rm (say daan ya estandarte na bansa ya GB/T 228-1987 et ibabaga ton say simbolo na tensile strength et σb), tan say yunit et MPa.

 

Yield strength (YS): Say kritikal ya balor na stress pian naala so materyal. Say yield strength et say yield limit na metal ya materyales no sikatoy ondalan ed yield phenomenon, salanti, say stress ya onsusumpad melag ya plastic deformation. Parad saray metal ya anggapoy mapatnag ya yield phenomenon, say stress value ya pansengegan na 0.2% ya residual deformation et nidepinsa bilang say yield limit to, ya tatawagen ya conditional yield limit o yield strength. No walay puersa ya mas baleg nen say sayan limitasyon ya onkiwas ed satan, say parte et permanentin nauman; no mas abeba nen say saya, say parte et ompawil ed datin kipapasen to.

 

Elongation rate: Say porsiento na kabuoan ya deformation ΔL na specimen kayari na tensile fracture ed orihinal ya gauge length L: δ=ΔL/L × 100%. Say atagey o abeban elongation rate et mangipapanengneng na pakayari na materyal ya mangawat na enerhiya legan na proseso na pangiyaplika na puersa tan say pakayari na materyal ya man-deformate na plastik. No mas atagey so elongation rate, mas baleg so permanentin deformation ya nasarag na materyal legan na proseso na pangiyaplika na puersa, ya mangipapanengneng na mas maong ya plastic deformation ability, ya matukoy ed saray senaryo na engineering ya mankaukolan na atagey ya inka-tough; bangta saray materyales ya abebay elongation rate et mangipapatnag na inka-brittle tan mainomay ya biglan nabali.

 

Pansukimat ed inkaawet: Say inkaawet et say pakayari na sakey a materyal ya ag-onloob ed tapew to. Saray kaslakan ya paraan na panagsukimat ed inka-malet et kaiba so Brinell hardness (HB), Rockwell hardness (HR), tan Vickers hardness (HC). Say Brinell hardness et matukoy ed saray plastik ya materyales, say Rockwell hardness et matukoy ed saray metal ya materyales, tan say Vickers hardness et matukoy ed mas manipis iran materyales odino melag iran subok ed lugar. Say magaspang a panangikompara ed baetan da et nayarin gawaen base ed eksperiensya tan kondisyon na subok.
