韧性差 meaning in English

ductility contrast

Sintered ndfeb has excellent magnetic properties with low price while the strength and toughness are poor which result in poor machinability , and it is easy to be broken . so they can not be used in areas with impact
但是,这种材料强度和韧性差,机械加工困难,应用过程中容易掉角开裂,特别是在一些有冲击振动载荷的领域应用受到限制。
Pp , as a kind of universal plastic , has some shortcomings , such as , the brittleness in low temperature , the low tenacity , aging , and so on . pp is not perfect in property and must be modified in order to be used widely
聚丙烯( pp )作为通用塑料，具有低温脆性、韧性差，易老化等缺点，在性能上还不完善，需进行改性才能得到更好的应用。
Plastic strain first starts from ambient of the porphyroblast , and then develops to rims of porphyroblast and gradually transfers to the centers of porphyroblasts . the brittle remains in the central parts of porphyroblasts come to be decreased through the plastic deformation development , which is accordance with the banding of intensity in many mylonitization zones on wild occurrences and observation in the fabrics of mylonitization rocks under microscope
长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。
