Key Technology yeBeryllium Copper (Kupisa kurapwa)
Kupisa kurapa ndiyo inonyanya kukosha maitiro eiyi emaitiro system. Nepo ese emhangura awori akaomeswa nekutonhora kushanda, bheryllium mhipuru yakasarudzika mukuwomererwa nekukasira kupisa kupisa kwekudziya kwekushisa. Inosanganisira matanho maviri ekutanga. Yokutanga inonzi mhinduro inowedzera uye yechipiri, yakatsvaira kana zera rakaomesa.
Mhinduro inosimbisa
Kune akajairwa Alloy Cube1.9 (1.8- 2%) Alloy inopisa pakati pe720 ° C na 860 ° C. Panguva ino iyo yaive neBeryllium ndeye "yakanyungudutswa" muCopper Matrix (ALPHA chikamu). Nekukurumidza kudzima kumhepo tembiricha iyi yakasimba mhinduro yekugadzirisa inochengetwa. Izvo zvinyorwa panguva ino zvakapfava uye zvakanyorova uye zvinogona kutonhora zvakanyanya kushandirwa nekudhirowa, kugadzira kutenderera, kana kutonhora musoro. Mhinduro yekunyora inoshandisa mashandiro ari chikamu chechiga chegayo uye hahushandiswe nemutengi. Tembiricha, nguva yeku tembiricha, quench rate, saizi yeGirairo, uye kuomarara kwese kwakaoma paramita uye kwakadzorwa zvakasimba neTankii.
ZIVA HOTHEST
ZIVA Kuomesa Kwazvo Kunosimbisa Simba reMusoro. Kuita uku kunowanzoitwa pakudziya pakati pe200 ° C uye 540 ° C zvose zvichienderana neAlloy nehunhu hwaunoda. Kutenderera uku kunokonzeresa beryllium yebhertium kuti isarure sebherinellium yakapfuma (GAMMA) chikamu muMatrix uye pamiganhu yezviyo. Iko kuumbwa kweizvi chiratidzo chinokonzera kuwedzera kukuru kwesimba rekunyama. Iyo mwero wezvemakaniki emakina anowanikwa akatsunga nekudziya uye nguva yeku tembiricha. Inofanirwa kuzivikanwa kuti Beryllium Copper haina kana tembiricha tembiricha yekukwegura.
