HFMI treatment doubles wear resistance of high-manganese steel hardfacing
High-frequency mechanical impact (HFMI) treatment significantly enhances the wear resistance of high-manganese steel hardfacing by inducing microstructural changes that promote a synergistic hardening effect.
Journal of Manufacturing and Materials Processing · 2026
Key Findings
- 01HFMI treatment leads to twinning, increased dislocation density, and a higher volume fraction of ε and α′-martensite in the hardfacing deposits.
- 02Microhardness increased significantly (2-3 times) after HFMI treatment.
- 03Scratch tests showed reduced restored depths and a 36–68% decrease in wear rate after HFMI.
- 04Wear mechanisms shifted from plastic deformation-related wedge/pile-up formation to ploughing after HFMI treatment.

Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive material characterization techniques used (XRD, SEM, nanoindentation).
- +Direct measurement of wear rate through scratch testing and analysis of wear mechanisms.
Limitations
The effectiveness of HFMI treatment might be dependent on the specific geometry and thickness of the hardfacing layer.
Reliability & validity
The use of multiple characterization techniques and quantitative wear measurements contributes to the reliability and validity of the findings. However, the specific wear mechanisms identified might be context-dependent.

Paragraph starter
The research by Trembach et al. (2026) demonstrates that High-Frequency Mechanical Impact (HFMI) treatment can significantly enhance the wear resistance of high-manganese steel hardfacing by inducing microstructural changes, such as increased dislocation density and martensite formation, leading to a doubling of microhardness and a substantial reduction in wear rate. This highlights the potential of targeted surface treatments to improve the durability of critical components.
