Caterpillar's Spatial Metamorphosis: Heavy Equipment Manufacturing in the 21st Century

Sociology Lens, Volume 39, Issue 2, Page 345-358, June 2026.
ABSTRACT Caterpillar Inc., the world's largest heavy equipment manufacturer, grew rapidly in the 20th century before a crisis of overproduction in the early 1980s threatened its survival. In response, it launched the $2.8 billion “Plant with a Future” (PWAF) program, a sweeping material and ideological overhaul that remade the firm for the post‐Fordist

Population of Nonmetallic Inclusions in Liquid High‐Silicon Electrical Steel in Contact With MgO–C Refractories Based on Recyclates and Environmentally Friendly Binders

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...
