This paper aims to explore the development of the US steel industry from the 19th to the 20th century by applying the Schumpeterian perspective on the concept of creative destruction. It introduces Game Theory as a means to describe patterns of strategic situations and entrepreneurial decision-making in an emerging industry.

Based on a narrative literature review of Schumpeter’s concept of creative destruction, four historical case studies have been designed. These historical case studies build the basis for game-theoretically analysis and evaluation. In doing so, the authors identify games with different payoff matrices that take place while an industry emerges, reflecting different layers of creative destruction.

Emerging industries, as this paper highlights, go through several stages of development until they reach full maturity. With Schumpeter, these stages can be studied through an entrepreneurial lens, highlighting different patterns of decision-making in each respective stage. This paper adds to a better understanding of emerging industries. Furthermore, this paper provides a methodological repertoire that can also be applied to other cases as well, such as the emergence of contemporary digital industries.

The paper provides a horizontal overview of how Game Theory can be applied to analyze industrial epochs and how the concept of creative destruction works in industry and transforms industry. It introduces Game Theory to management and business history as a sound methodological base to analyze and evaluate strategic situations and entrepreneurial decision-making.

The paper presents a comprehensive method to act in the different stages of an industrial epoch and how to act. The games applied in the particular layers of creative destruction give an insight into the analysis of strategic situations and strategic decision-making in the industry.

This paper provides a horizontal perspective on strategic games that can be used as an analysis methodology in the field of entrepreneurship and applied in contemporary industries. It connects historical cases out of the US steel industry with Schumpeter’s concept of creative destruction and Game Theory.

This study aims to assess the feasibility of laser powder bed fusion (LPBF) processing using as-received gas-atomized spherical Neodymium-Iron-Boron (NdFeB) powder (17–68 µm), compared to literature methods that sieve to a narrow size range (<40 µm).

The research involves single track and layer printing, process optimization and subsequent heat treatment and magnetic annealing. The experimental approach includes conducting systematic printing trials to assess the impact of various parameters on printed track and layer quality, and refining printing parameters through iterative testing. Heat treatment and magnetic annealing are applied to achieve the desired magnetic properties.

A minimum linear energy density of 0.10 J/mm is required for continuous track formation, with track width largely unaffected by varying linear energy densities. An optimal hatch spacing of approximately 42% overlap avoids layer defects, with 0.10 mm spacing suitable for layer thicknesses between 30 and 80 µm. A stable processing window for energy density (EA) of 0.6–1.0 J/mm² was identified, allowing cuboid printing despite some discontinuous tracks, indicating potential fusion issues. Maximizing volumetric energy density (EV) within this range correlates positively with part density, achieving 92% density, coercivity of 490 kA/m and remanence of 496 mT. Post-treatment, density increased to 96%, coercivity to 582 kA/m and remanence to 544 mT.

This study fills a significant gap in LPBF literature for NdFeB by using the original wider size range of spherical powder without sieving, demonstrating improved cost-effectiveness, material efficiency and build efficiency. These findings offer practical recommendations for addressing the challenges related to LPBF processing of NdFeB powder.
