高应变率拉伸和压缩测试和介孔Invar(FENI36)的性能(FENI36)原料挤出产生的基质句法泡沫
摘要
The present study investigates the high strain rate behavior of mesoporous metal matrix syntactic foams focusing on the dependence of compressive and tensile properties on strain rate. The strain rate range, covered both in compression and tension, extends from quasi-static conditions or 10−3 s−1 to 103 s−1. Syntactic foams based on commercial high strength hollow glass microspheres and Invar (FeNi36) matrix are produced by means of feedstock extrusion and subsequent sintering. Levels of glass microsphere addition examined are 5 and 10 wt%, respectively, corresponding to approximately 40 and 60 vol% of microspheres in the initial mix prior to sintering, and considering the metal and filler fraction only. Reference samples containing no microsphere addition have been included in the study. Mechanical testing is accompanied by metallographic examinations.

本文研究了介孔金属基复合泡沫塑料的高应变率行为,重点讨论了压缩和拉伸性能对应变速率的依赖性。在压缩和拉伸两种情况下,应变率范围从准静态条件或10 -3 s -1到10 s 3 s SUP -1 / SUP。基于市售高强度中空玻璃微球和Invar(FeNi36)基体的复合泡沫材料通过原料挤出和随后的烧结来制造。加入的玻璃微球的添加量分别为5wt%和10wt%,分别相当于烧结前最初混合物中约40和60vol%的微球,并且仅考虑金属和填料部分。研究中包括了不含微球的参考样品。机械测试伴随有金相检查。
