Mbụ, na n'ibu Njirimara nke forgings
The n'ibu Njirimara nkeforgingsna-ekpebisi ike dị ka ngwaahịa chọrọ. A na-ekewa ụzọ nnwale ahụ n'ime ule ike ike, ule tensile, ule mmetụta na ule ike ọgwụgwụ.
1. Nnwale ike ike
Isi ike bụ nrụrụ nke elu ihe, ọ bụ ndeksi na-atụ ihe igwe dị nro siri ike. Isi ike na ndị ọzọ n'ibu Njirimara nwere ụfọdụ esịtidem mmekọrịta, otú ndị ọzọ n'ibu Njirimara nke ihe nwere ike mere atụmatụ site ekweghị ekwe uru. Nnwale siri ike adịghị mkpa ịkwadebe ihe nlele pụrụ iche, ma ọ bụ na ọ gaghị emebi ihe atụ ahụ, ya mere ule siri ike bụ ihe a na-ejikarị eme ihe na mmepụta nke usoro nyocha ihe onwunwe.
Ụzọ ule ike siri ike nke a na-ejikarị na ụkpụrụ dị iche iche bụ: Brinell hardness (HB), hardness Rockwell (HRC), Vickers hardness (HV), Shore hardness (HS), na onye na-anwale ike ike kwekọrọ.
2. Nnwale tensile
Site n'itinye ihe nrịbama ahụ na ihe atụ nke ụdị ụfọdụ site na igwe ihe eji eme ihe, a na-atụle nrụgide elongation nke nha, ebe mkpụrụ osisi, ike ike, elongation na mbelata nke ngalaba nke ihe igwe.
3. Nnwale mmetụta
Enwetara mmetụta siri ike nke ígwè ahụ site na iji pendulum na-agba ọsọ na-emetụta ihe atụ ahụ na notch.
4. Nnwale ike ọgwụgwụ
Enwere ike tụọ oke ike ọgwụgwụ na ike ike nke igwe mgbe nrụgide ugboro ugboro ma ọ bụ na-atụgharị.
Abụọ, nyocha nke adịchaghị emebi emebi
Enwere ike ikewa nnwale na-adịghị emebi emebi na nnwale redio, nnwale ultrasonic, nnwale ihe ndọta, nnwale seepage na nnwale eddy ugbu a. A na-ejikarị forgings eme ihe na nyocha ultrasonic na nyocha ihe ndọta.
1. Nnyocha nyocha nke ultrasonic
Ultrasonic ife (ugboro bụ n'ozuzu karịa 20000Hz) ga-atụgharị uche na refract na interface nke dị iche iche ihe. Ya mere, ọ bụrụ na enwere ntụpọ nke ihe dị iche iche na ihe siri ike, a ga-emepụta ntụgharị uche na attenuation. Enwere ike ikpebi ịdị adị nke ntụpọ site na akara waveform.
Maka nnukwu na ọkaraforgings, Nnwale ultrasonic bụ otu n'ime ụzọ dị mkpa nke ule na-adịghị emebi emebi.
2. Magnetik urughuru nnyocha
Enwere ike inyocha ntụpọ ndị dị ka mgbawa, oghere na ntinye ndị na-abụghị metallic na na nso elu nke akpụ akpụ site na nyocha ihe ndọta. N'ihi ngwá ọrụ ya dị mfe, ọrụ dị mfe na nghọta dị elu, a na-ejikarị usoro a iji nwalee obere na ọkara-sized anwụ forgings na-emepụta na nnukwu quantities.
Atọ, obere ike na mgbaji ule
Nnyocha ike dị ala bụ ihe nlele mgbe ụfọdụ nhazi, wee jiri anya gba ọtọ na 10 ~ 30 ugboro iko na-ebuli elu iji lelee ihe nlele ahụ, ka ịchọta ntụpọ nke igwe anaghị agba nchara. Enwere ike nyochaa Streamline, dendrite, rụrụ arụ, naphthalene, mgbaji nkume na ntụpọ ndị ọzọ site na ịcha ihe nlele wafer na etching acid. Iji chọpụta nkewa, karịsịa nkesa na-enweghị isi nke sulfide, a na-eji usoro mbipụta sulfur mee ihe.
Anọ, nyocha ike dị elu
A ga-eme ka forging igwe anaghị agba nchara ka ọ bụrụ ihe nlele ụfọdụ n'okpuru microscope iji lelee forgings dị n'ime (ma ọ bụ mgbaji) na steeti nzukọ ma ọ bụ ntụpọ microscopic. Enwere ike ịlele nhazi nke dị n'ime na ntinye nkesa nke forging site na ịcha ihe nlele ogologo. Enwere ike nyochaa ntụpọ dị n'elu dị ka decarburization, nke na-enweghị isi, carburized na akwa akwa siri ike site na ịcha ihe nlele transverse.
