A Short Review on Fracture Mechanisms of Mechanical Components Operated under Industrial Process Conditions: Fractographic Analysis and Selected Prevention Strategies

Abstract

An insight of the dominant fracture mechanisms occurring in mechanical metallic components during industrial service conditions is offered through this short overview. Emphasis is given on the phenomenological aspects of fracture and their relationships with the emergent fracture mode(s) with respect to the prevailed operating parameters and loading conditions. This presentation is basically fulfilled by embracing and reviewing industrial case histories addressed from a technical expert viewpoint. The referenced case histories reflected mainly the author's team expertise in failure analysis investigation. As a secondary perspective of the current study, selected failure investigation and prevention methodological approaches are briefly summarized and discussed, aiming to provide a holistic overview of the specific frameworks and systems in place, which could assist the organization of risk minimization and quality enhancement.

Examination of Formability Properties of 6063 Alloy Extruded Profiles for the Automotive Industry

“…At the microscopic level, voids are generated around second phase particles, and at the centre of the necked region, where the stress triaxiality is maximum. A recent review of the fracture mechanisms is presented in [22]. It is noteworthy that higher amount of intergranular fracture relatively to dimple fracture is observed on the surface region of the 2.9 mm sample.…”

Failure Mechanisms in Alloys

“…Reference Structural and pipeline steels [1,5,9,13,16,20,22,27] Cast iron [14,19] Special resistance and stainless steels [3,4,9,11,17,18,21,23,24] Wear resistant coatings and surface layers [24,27]…”

“…"Progressive" or "delayed modes of failure" possess exceptional interest in various industrial sectors, such as the chemical, mechanical, and manufacturing industries and in plant machinery. Four basic categories can be distinguished(Figure 2a): a.Creep and Creep Fatigue failure modes[2,9,17,23]; b.…”

Prediction of Bake Hardening Behavior of Selected Advanced High Strength Automotive Steels and Hailstone Failure Discussion

“…In the literature [34][35][36] there are applications of failure studies in steel-maker organizations. The detailed procedure, according to [37,38] aims to guide quality engineers and practitioners and to offer consistent results towards failure prevention and quality improvement.…”
