Characterization of Nanosized Carbide Precipitates in Multiple Microalloyed Press Hardening Steels
Metals, 2023 Press hardening steel standardly relies on titanium microalloying for protecting boron from being tied up by residual nitrogen. This practice safeguards the hardenability effect of boron during die quenching.

Effect of microalloying on the toughness of metallic glasses [PDF]
, 2012 The effect of microalloying on the toughness of Cu-Ti-based metallic glasses is explored. Minor additions of Si and Sn in glass former Cu_(47)Ti_(34)Zr_(11)Ni_8 known to improve glass-forming ability are found here to sharply decrease toughness. The drop

Titanium microalloyed steels [PDF]
Ironmaking & Steelmaking, 2018 This review considers the compositions, the main process routes, microstructure and structural properties of microalloyed steels. The background and brief history are followed by sections dealing with aspects of precipitation, which control grain size and dispersion strengthening in ferrite–pearlite steels, the approaches to modelling thermomechanical ...
