Tungsten is not shock resistant. It is brittle at low temperatures and can become even more brittle when impure or contaminated.
This brittleness is due to its ductile-to-brittle transition temperature (DBTT) being higher than room temperature. This makes it difficult to work with and prone to breakage under impact.
5 key points to consider
1. Brittleness at Low Temperatures
Tungsten's brittleness at low temperatures is a significant challenge in its use and fabrication.
The material's DBTT, which is usually above room temperature, means that it exhibits poor ductility and is very brittle under typical ambient conditions.
2. Impact on Applications
This characteristic makes it unsuitable for applications where shock resistance is required. It can easily fracture or shatter upon impact.
3. Effect of Impurities
Additionally, tungsten's brittleness can be exacerbated by impurities or contamination.
When tungsten is not pure, it becomes even more difficult to work with and more prone to breakage.
4. Machining Challenges
This is particularly problematic in machining and shaping processes. The material's brittleness can lead to failure or damage to the tools used.
5. High-Temperature Properties
The reference materials provided do not explicitly mention shock resistance but highlight tungsten's high melting point, low vapor pressure, and shape retention at high temperatures.
These properties are beneficial in high-temperature applications. However, they do not translate to shock resistance.
Instead, the materials discuss the challenges of working with tungsten, including its difficulty in machining and its brittleness. These are indicative of a lack of shock resistance.
