Kubera ko amakuru yavuye kuriyi mirongo yakoreshejwe mugutoza umuyoboro, ntabwo bitangaje kwitegereza ibyahanuwe cyane.
Ikigeragezo gifatika FLC na ANFIS guhanura umurongo mubihe bitandukanye bya martensite. Iyi mirongo ikoreshwa mugikorwa cyamahugurwa.
Moderi ya ANFIS ntabwo izi uko byagenze kurugero rwanyuma. Kubwibyo, twagerageje ANFIS yatojwe kuri FLC dutanga ingero hamwe na martensite ya 25,6%. Ku mutini. 11 yerekana ubuhanuzi bwa ANFIS FLC kimwe na FLC igerageza. Ikosa ntarengwa hagati yagaciro kateganijwe nagaciro kagereranijwe ni 6.2%, iruta agaciro kateganijwe mugihe cyamahugurwa no kwemeza. Ariko, iri kosa ni ikosa ryihanganirwa ugereranije nubundi bushakashatsi buteganya FLC mubyukuri37.
Mu nganda, ibipimo bigira ingaruka kumiterere byasobanuwe muburyo bwururimi. Kurugero, "ingano nini igabanya guhinduka" cyangwa "kongera ubukonje bukora bigabanya FLC". Iyinjiza kumurongo wa ANFIS murwego rwa mbere ishyirwa mubyiciro byindimi nkibiri hasi, iciriritse na hejuru. Hariho amategeko atandukanye yibyiciro bitandukanye kumurongo. Kubwibyo, mu nganda, ubu bwoko bwurusobe rushobora kuba ingirakamaro muburyo bwo gushyiramo ibintu byinshi mubisobanuro byindimi no gusesengura. Muriyi mirimo, twagerageje kuzirikana kimwe mubintu byingenzi biranga microstructure ya austenitis ibyuma bitagira umuyonga kugirango dukoreshe ibishoboka bya ANFIS. Ingano ya martensite iterwa na stress ya 316 ningaruka zitaziguye zakazi gakonje kinjiza. Binyuze mu bushakashatsi hamwe nisesengura rya ANFIS, byagaragaye ko kongera igipimo cya martensite muri ubu bwoko bwibyuma bya austenitike bitagira umwanda biganisha ku kugabanuka gukabije kwa FLC yisahani 316, ku buryo kongera umubare wa martensite uva kuri 7.8% ukagera kuri 28.7% bigabanya FLD0 kuva 0.35. kugeza kuri 0.1. Kurundi ruhande, umuyoboro wa ANFIS watojwe kandi wemejwe urashobora guhanura FLC ukoresheje 80% yamakuru yubushakashatsi aboneka hamwe nikosa ntarengwa rya 6.5%, akaba ari intera yemewe yamakosa ugereranije nubundi buryo bwa teoritiki nubusabane bwa fenologiya.
Imibare ikoreshwa kandi / cyangwa yasesenguwe mubyigisho byubu iraboneka kubanditsi babisabwe babisabye.
