“Characterization of Tensile and Shear Loading on Indented PC-Strand Cable Bolts,” by Anand Bhagwat and Stephen C. Tadolini, Minova USA, Inc.; and Steven Derycke, NV Bekaert SA
PC strands are becoming widely acceptable as a roof support system in underground mining applications for their superior strength and flexibility. Laboratory testing was completed to evaluate the tensile and shear strength of individual wires and completely wound PC-strand cables. Both smooth wires and the recent anchorage enhancement innovation of indentation were evaluated and compared. The results demonstrate that the difference between smooth and indented wires is statistically insignificant, and that indentation does not adversely affect strand properties and performance.

“Quenched and Partitioned Steel Wires: Process, Characterization, and Properties,” by Christophe Mesplont and Walther Van Raemdonck, NV Bekaert SA
Steel wires with a microstructure containing martensite and retained austenite were produced with the Quenching and Partitioning (Q&P) thermal process, a modified version of the Quenching and Tempering (Q&T) process. The Q&P wires exhibited high “total elongation – at” x “tensile strength – N/mm²” product, above 20000 %. N/mm². This multiplication product is two to three times higher than with Q&T. The higher elongation was due to the TRIP (Transformation Induced Plasticity) effect during plastic deformation. The results reveal application possibilities especially where high energy absorption behavior is required.

“New Process Metallurgy Developments for the Production of Steel Wire Rods,” by Steven Jansto, CBMM North America Inc.
Improvements in mechanical property performance often result in higher production cost. Recent process metallurgy technology is applied in wire products to address this demand. The process influence is now balanced with improved wire rod microstructure, properties, and grain size consistency. The complementary benefit of micro-additions of niobium refines the microstructure, reduces scrap, and improves drawability and robustness. Case examples involve pre-stressed concrete wire rod, tire cord, and medium carbon spring steels.

It focuses on production line design that addresses the following key process features for efficient heat treatment of austenitic and ferritic stainless material: required temperature profile and cooling rates, tempering and slow cooling of ferritic materials, rapid cooling of austenitic grades, material handling and wire guiding through heat treatment line, and process gas alternatives and atmosphere requirements.11:15 AM-11:50 AM
“Evaluation of Mechanical Properties of Wire Rod by Shear Punch Test,” by Likhith Nalluri and Ramesh K. Guduru, Lamar University; and Roberto Perez, Leonardo Radicchi S. Cunha, Peter Power, Bhaskar Yalamanchili, and Thad Boudreaux, Gerdau Long Steel North America
For the first time, a miniaturized specimen testing technique, “shear punch test (SPT),” was implemented to study the mechanical properties of wire rods. SPT can predict tensile properties as well as localized variations in the mechanical properties. Therefore, the discs from the wire rods were tested at the center and mid-radius to investigate the variation in their shear strength correlating with their microstructures and possibly the chemistry. This paper presents those results.

“Our 3-D Printed Future: How to Position Yourself and Your Organization to Successfully Navigate This Historic Shift,” by Rick Smith, 3-D Printing Expert, Bestselling Author
3-D printing production will change the world more in this century than the industrial revolution has over the last 300 years. So says author and entrepreneur Rick Smith in this provocative and entertaining talk based on his upcoming new book. Smith lays out a compelling framework to explain the growth and inevitability of 3-D printing as it permanently displaces conventional manufacturing. He reveals a brave new future where objects are 3-D printed using plastics and steel, skin and stem cells, chocolate and Kevlar, where pipes are printed that can automatically repair themselves and batteries are printed the size of a grain of sand, where global supply chains collapse, and the wealth of nations is flipped on its head.
In pursuit of this radical future, Smith introduces audiences to some of the modern pioneers of 3-D printing while also moving further back in history to the fascinating cast of characters who shaped other great technological shifts. This talk answers two questions that strike at the heart of every leader in every organization: How will the future unfold in front of us? And how can we position ourselves and our organizations to successfully navigate this historic shift to our greatest benefit?

“Moving Toward Visible Difference and Beyond: Imaging-Based Surface Quality Control for Rod and Wire,” by Tzyy-Shuh Chang and Howard Huang, OG Technologies Inc.; and Jianjun Shi, Georgia Institute of Technology
Applications of rod and wire, particularly those subject to substantial processing, demand high surface quality to avoid product failure during processing or use. In recent years, imaging-based equipment has been applied not only to the hot rolling wire rod mills, but also in wire peeling and drawing facilities. The “image advantage” provides the foundation of visibility, a key capability for detecting and verifying very fine surface anomalies. Additionally, the visibility also facilitates timely identification of process/equipment issues such as roll and die wear, among others.
