Abstract

Purpose

This study aims to investigate the circumstances where the positive influences of leader’s self-confidence are weakened in situations of conflict management (CM) arising due to innovation implementation. Specifically, this study tests the moderating influence of financial slack, internal opposition posturing and performance feedback on the relationship between self-confidence and conflict management styles (CMS). The findings are not complete.

Design/methodology/approach

This experimental study was conducted in two stages: In Stage 1, the authors studied moderating effects of financial slack (sound/unsound) and internal opposition posture (encouraging/ discouraging) on the relationship between leader’s self-confidence and CMS, namely, dominating, integrating and avoiding. In Stage 2, the authors studied the moderating effect of performance feedback (success/failure) on the relationship between leader’s self-confidence and three CMS. Data were collected from 268 senior-level Indian managers in Stage 1, out of which 235 managers also responded in Stage 2. These participants assumed the positions of chief executive officers (CEOs) within major Indian manufacturer specializing in electrical components, enabling us to empirically test the proposed model. Furthermore, a qualitative analysis of 10 semistructured interviews with Indian CEOs were conducted to enrich the discussion of the results.

Findings

Leader’s self-confidence determined the three CMS with highly self-confident leaders displaying irrational behavior in persisting with innovation through dominating style. Internal opposition posture and performance feedback exerted main effects on dominating style.

Research limitations/implications

This study supports behavioral decision theory of firm and escalation of commitment theory.

Practical implications

This study underscores the need for personality and self-awareness training amongst senior managers to mitigate irrational behavior due to excessive self-confidence and enhanced effective CM.

Originality/value

This study identifies a crucial boundary condition where high self-confidence in innovation implementation may lead to irrational behavior and ineffective CM.

Abstract

Purpose

This paper aims to examine dissimilar joints for various applications in chemical, petrochemical, oil, gas, shipbuilding, defense, rail and nuclear industry.

Design/methodology/approach

This study examined the effects of cold metal transfer welding on stainless steel welds for 316L austenitic and 430 ferritic dissimilar welds with ER316L, ER309L and without (autogenous) fillers. The microstructural observation was done with an optical microscope. The mechanical test was done to reveal the strength, hardness and toughness of the joint. The electrochemical polarization tests were done to reveal intergranular and pitting corrosion in the dissimilar joints.

Findings

This microstructural study shows the presence of austenitic and ferritic phases with vermicular ferrite for ER309L filler weld, and for ER316L filler weld specimen shows predominately martensitic phase in the weld region, whereas the autogenous weld shows lathy ferrite mixed with martensitic phase. Mechanical test results indicated that filler welded specimen (ER316L and ER309L) has relatively higher strength and hardness than the autogenous weld, whereas ER316L filler weld exhibited the highest impact toughness than ER309L filler weld and lowest in autogenous weld. The electrochemical corrosion results displayed the highest degree of sensitization (DOS) in without filler welded specimen (45.62%) and lower in case of filler welded specimen ER309L (4.95%) and least in case of ER316L filler welded specimen (3.51%). The high DOS in non-filler welded specimen is correlated with the chromium carbide formation. The non-filler welded specimen shows the highest pitting corrosion attack as compared to the ER316L filler weld specimen and relatively better in ER309L filler welded specimen. The highest pitting corrosion resistance is related with the high chromium content in ER309L composition.

Originality/value

This experimental study is original and conducted with 316L and 430 stainless steel with ER316L, ER309 and without fillers, which will help the oil, shipbuilding and chemical industries.
