Metallurgical Laboratory - Microhardness Testing

Capabilities Includes:

• Comparison of welded area relative to base metal.
• Great indicator of strength and brittleness.
• Indicates areas of welded structures that are most susceptible to fatigue failure and cracking in use.
• Used in conjunction with other testing methods, can provide a way to gain feedback on joining parameters.

Examples:

1. Vickers Indents

• Widely Accepted Hardness Test

Advantages:

• Can indent and provide a single continuous scale for materials of any type.
• No need to convert hardness scales or change indenters per material.
• All results tested at a specific load are directly comparable.

2. Knoop Indents

• Specialized Hardness Test

Advantages:

• Small diagonal allows many indents to be put close together.
• Continuous scale.
• Possible to indent thin coatings.
• Results are also directly comparable.

Using automated systems allow us to indent and measure much faster. In addition, indent grids can be made that generate a Hardness Map. This gives our customers a complete understanding of what is happening in their process.
