O QUE SIGNIFICA SUPERPLASTIC EM INGLÊS
Superplasticidade
Na ciência dos materiais, a superplasticidade é um estado em que o material cristalino sólido é deformado bem além do seu ponto de ruptura usual, geralmente em cerca de 200% durante a deformação por tração. Tal estado geralmente é alcançado em alta temperatura homóloga, normalmente metade do ponto de fusão absoluto. Exemplos de materiais superplásticos são alguns metais e cerâmicas de grão fino. Outros materiais não cristalinos, tais como vidro de sílica e polímeros, também se deformam de forma semelhante, mas não são chamados de superplásicos, porque não são cristalinos; Em vez disso, sua deformação é muitas vezes descrita como fluxo Newtoniano. O material superplasticamente deformado fica mais fino de uma maneira muito uniforme, em vez de formar um "pescoço" que leva à fratura. Além disso, a formação de microvoides, que é outra causa de fratura precoce, é inibida. Em metais e cerâmicas, os requisitos para que sejam superplásticos incluem um tamanho de grão fino e uma fina dispersão de partículas termicamente estáveis, que agem para fixar os limites de grãos e manter a estrutura de grão fino nas altas temperaturas e Existência de duas fases necessárias para a deformação superplástica .
definição de superplastic no dicionário inglês
A definição de superplástico no dicionário é muito facilmente moldada a altas temperaturas sem fraturação. Outra definição de superplástico é tal metal, liga, etc.
