韧性 1.(指顽强持久的精神) tenacity 富有韧性 with tenacity; 韧性很强 very tenacious; 我们要学习鲁迅先生韧性的战斗精神。 we must learn from the tenacious fighting spirit of lu xun.2.[力学] toughness; ductility; ductibility
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。
