Mechanical testing of materials

Purpose

 

• Characterization of metallic and ceramic materials by testing important mechanical properties such as strength, hardness, fracture toughness and creep deformation at room and high temperature conditions.
• Development of accompanying and useoriented tests in accordance with existing standards and customer ́s requirements.

 

Test methods

 

Ambient temperature conditions

• Bending, compression, tensile strength
• Determination of fracture toughness with indentation and SEVNB method
• Fractographic investigation and determination on the presence of defects by dye penetration
• Determination of elastic modulus in bending
• Measurement of biaxial strength
• Statistical analysis
• Vickers and Knoop hardness test between 0.98 N and 491 N
• Production of reference blocks made of advanced ceramics

High-temperature conditions

• Test temperature up to 1600 °C in air and vacuum
• Bending and compression strength
• Creep test in bending and compression
• Vickers and Knoop hardness test between 9.8 N und 294 N
• Determination of fracture toughness and subcritical crack growth behavior
