Manganese dade (manganese a ɛkorɔn) .
Manganese dadeɛ a ɛkorɔn a wɔtaa de di dwuma wɔ China brand ne ne kɛseɛ a wɔde di dwuma ne: ZGMN13-1 (C 1.10%~1.50%) ma nsunsuansoɔ a ɛba fam no afã, ZGMN13-2 (C1.00%~1.40%) ma afã a ɛyɛ mpapahwekwa, ZGMN13-3-3 (C0.90% ~ 1.30%) for complex, Zgn ama afã horow a ɛwɔ nkɛntɛnso kɛse. Manganese a ɛwɔ atifi hɔ no mu no yɛ 11.0% ~ 14.0%.
Wɔ awɔw bere mu deformation a ɛwɔ impact load no, dade no yɛ den denam dislocation density a ɛkɔ soro kɛse, dislocation delivery, dislocation plug deposition, ne dislocation ne solute atom ahorow no nkitahodi so. Eyi yɛ ade titiriw nti a wɔyɛ den ho adwuma. Ade foforo a ɛho hia nti ne sɛ layer mfomso ahoɔden a ɛwɔ manganese a ɛkorɔn autenite no sua, na ɛyɛ mmerɛw sɛ stacking layer mfomso wɔ deformation bere mu, na ɛnam so ma tebea horow ma formation of ε martensite ne deformation twin a wɔyɛ. High density dislocation, dislocation deposition ne entanglement taa tumi hu wɔ deformation hardening layer a ɛyɛ amanne kwan so manganese a ɛyɛ den no mu.Wε a ɛda adi ma martensite ne deformed twin ma dade no yɛ den sɛ ɛbɛsɛe, titiriw esiane sɛ nea etwa to no ho hia kɛse nti. Nneɛma a ɛwɔ atifi hɔ no ma manganese dade a ɛkorɔn a ɛyɛ den no yɛ den kodu baabi, na ɛyɛ den kɛse.
High manganese steel yɛ mmerɛw sɛ ɛbɛyɛ den, enti ɛyɛ den sɛ wobedi ho dwuma, castings dodow no ara, forging method processing kakraa bi pɛ. casting adwumayɛ a ɛkorɔn-manganese dadeɛ no ye. Dadeɛ a ɛyɛ nwini no sua (bɛyɛ 14 ()()℃), nsuo ne dadeɛ a ɛyɛ den no hyeɛ ntam kwan yɛ ketewa (bɛyɛ 50℃), dadeɛ a ɛma ɔhyew kɔ fam no sua, enti nsuo a ɛyɛ nsuo no yɛ papa, ɛnyɛ den sɛ wɔbɛhwie agu. Wire ntrɛwmu coefficient a ɛwɔ manganese dade a ɛkorɔn no yɛ dade a ɛho tew mmɔho 1.5 na ɛboro carbon dade mmɔho 2. Enti, sɛnea nne no ano yɛ den na nhama no so tew no yɛ akɛse bere a wɔretotow no, na ɛyɛ mmerɛw sɛ ɛbɛhaw na apaapae.
Sɛnea ɛbɛyɛ a manganese dadeɛ a ɛkorɔn no adwumayɛ bɛkɔ anim no, wɔayɛ nhwehwɛmu pii wɔ alloying, microalloying, carbon ne manganese content adjustment ne precipitation reinforcement treatment ho, na wɔde di dwuma wɔ production practice no mu. Mesostatic austenitic manganese dadeɛ a ɛda adi no bɛtumi ate carbon ne manganese a ɛwɔ dadeɛ no mu no so kɛseɛ na ama dadeɛ no deformation ne reinforcement no atu mpɔn, a wɔbɛtumi de adi dwuma wɔ adwumayɛ tebea a ɛyɛ adesoa a ɛkorɔn ne nea ɛba fam, a ɛyɛ dadeɛ a ɛkorɔn a ɛyɛ manganese no nkɔsoɔ foforɔ.

Saa dadeɛ yi mu duru bɛyɛ 7.87 ~ 7.98g/cm3. Esiane sɛ carbon ne manganese dɔɔso nti, dade a ɛma ɔhyew no kɔ so no nyɛ papa. Ɔhyew a ɛkɔ mu no yɛ 12.979W/ (m℃), bɛyɛ 1 / 3 wɔ carbon dade no mu.
