Mechanical testing of materials

Purpose

 

• Characterization of metallic and ceramic materials by testing important mechanical properties such as strength, hardness, creep deformation and fracture toughness 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 25 p and 50 kp
• Production of reference blocks made of advanced ceramics

High temperature conditions

• Test temperature up to 1500°C in air and vacuum.
• Determination of strength in bending and compression
• Creep test in bending and compression
• Vickers and Knoop hardness test between 1 kp and 30 kp
• Determination of fracture toughness and subcritical crack growth behavior with indentation and SEVNB method
