Temperature Dependent Deformation

Temperature Dependent Deformation

In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...

部落学 (tribology) 是一个学科.
机械工程机械工程

背景情况:

金属玻璃 (MGs) 具有出色的机械性能,使其适用于先进的技术应用.
它们无序的原子结构表明了潜在的零下工程应用.
关于MGs在零度以下温度下机械性能和磨损行为的研究有限.

研究的目的:

为了研究Zr基金属玻璃 (MG) 的磨损特性和机制,在零下 -50°C的温度下.
为了比较MGs在零下条件下的磨损性能与室温.
了解观察到的穿戴行为差异的根本原因.

主要方法:

系统评估基于Zr的MG的磨损特性和机制.
在特定零下温度 (-50°C) 进行的测试,并与室温数据进行比较.
磨损机制的分析,包括氧化,粘附和磨损.

主要成果:

与室温相比,MG在-50°C时的磨损率大约减少了60%.
在室温下,MGs形成了易碎的氧化物层,导致氧化,粘合剂和磨料磨损.
在零度以下的温度下,只观察到磨损性磨损,更高的弹性模量有助于改善耐磨性.

结论:

基于Zr的MG在零度以下的环境中表现出优越的耐磨性.
氧化物层的不形成和弹性模量增加是提高低温性能的关键因素.
这些发现为利用MG在零度以下的工程应用中提供了宝贵的见解,例如深空和极地勘探.
