Itekhnoloji yoNyango ePhakamileyo yoNyango lweTekhnoloji yoMveliso | Shangdong yueheng

Unyango lobushushu lulawula ii-metriniki lentsebenzo kubandakanya nobomi bokutya (i-L10), inxibe ukunganyangeki, kunye nokuzinza komgangatho. Imveliso yanamhlanje ifuna ± 3 ° C Ulawulo lobushushu kwaye Inkqubo ye-CPK≥1.33. Ulandelelwano oluPheleleyo: Ukukhuphela i-Anneiling → Ukucima → Ukucinywa kweqondo lobushushu.

Ukudluliselwa

INJONGO: Ukuphelisa uthungelwano lwe-carbide (≤grade 2), iFomu ye-Homogeneous Pearliite (i-Carbide Spiidiod ≥90%, i-DITE 0.2-0.6m 179-207 hb. IProtokholi yeNqanaba amabini:

• Inqanaba loku-1: 790 ± 10 ° C
• Inqanaba lesi-2: 710 ± 10 ° 4-6H ijika elilawulayoIthintele i-puarlide ye-carfide

Iparameter ebalulekileyoUbungakanani beenkozo 7-8 (i-ATTM E112)

Inkqubo yokuqhubela phambili

Ityiwa yetyuwa (i-Bacl₂: KCL = 3: 1) okanye indawo yokukhusela (n₂-chūoh, i-oxygen probe ≤0.5%):

• I-GCR15 intsimbi: 845 ° 5 ° C × 1
• Ukupholisa i-kinetics kinetics: 800 → I-500 ° C / S (S (thintela ukuFumaneka kweFerrita), ukuphola kancinci ukuphola ngaphantsi kwe-300 ° C
• Ithagethi: I-Cryptocrystalline Marticie (> 95%, ubude benaliti) +

3.Ukushushu-ubushushu obushushu

I-150-180 ° C × 2-4h (± 3 ° C) ngaphakathi Ukunyanzelwa kwesithando somoya:

• I-bi-fe₂c
• I-Austerite Deations:> I-80% (i-XRD iqinisekisiwe)
• Imodeli yoncedo yoxinzelelo: σ_i_i-σ_ii_i

Iinkqubo ezi-4 kunye nezinto ezintsha

• Ukugcwala: 230 ± Ityuwa yetyuwa ye-10 → → i-baineine esezantsi (58-62 hrc, i-KCV≥50J / cm²)
• I-ring inzulu: -70 ° C × 4h (i-pitrogen ye-nitrogen), i-Austerite → Inguquko yeMartenation> 95%
• I-Laser Harding: I-1064nm yaveleth idale i-0.3mm Inamatyala, ↑ 40% Qhagamshelana nobomi bokudinwa
